Prenatal stress and externalizing behaviors in childhood and adolescence: A systematic review and meta-analysis.

Accumulating evidence suggests that psychological distress during pregnancy is linked to offspring risk for externalizing outcomes (e.g., reactive/aggressive behaviors, hyperactivity, and impulsivity). Effect sizes across studies have varied widely, however, due to differences in study design and methodology, including control for the confounding continuation of distress in the postnatal period. Clarifying these inconsistencies is necessary to guide the precision of prevention efforts and inform public health policies. A meta-analysis was conducted with 55 longitudinal studies to investigate the association between prenatal psychological distress (anxiety, depression, and perceived stress) and offspring externalizing behaviors. Results revealed a significant but small effect (r = .160) of prenatal distress on externalizing behaviors. The magnitude of the prenatal effect size remained largely unchanged after adjusting for postnatal distress (r = .159), implicating a unique effect of psychological distress during the prenatal period in the etiology of externalizing behaviors. Moderation tests showed that prenatal effects did not vary based on type and timing of psychological distress during pregnancy. Greater instability of distress from prenatal to postnatal periods predicted larger effects. Prenatal effects were comparable across most externalizing outcomes, consistent with the common comorbidity of externalizing spectrum disorders, although effects appeared smaller for nonaggressive rule-breaking (vs. aggressive) behaviors. Significant associations persisted across all developmental periods, appearing slightly larger in early childhood. We discuss these results in the context of developmental and psychobiological theories of externalizing behavior, offer preliminary clinical and public health implications, and highlight directions for future research including the need for longitudinal studies with more racially and socioeconomically diverse families.

Psychological Well-being across the Perinatal Period: Life Satisfaction and Flourishing in a Longitudinal Study of Black and White American Women.

Psychological well-being (life satisfaction and flourishing) during the perinatal period has implications for both maternal and child health. However, few studies have investigated the extent to which psychological well-being changes from preconception to postpartum periods, particularly among diverse samples of women. Using prospectively collected data from an ongoing longitudinal study, we investigated changes in two dimensions of psychological well-being from preconception to postpartum among 173 Black and White American women. Results showed that changes in life satisfaction (i.e., global quality of life) and flourishing (e.g., self-acceptance, sense of purpose) over the perinatal period were moderated by race. For life satisfaction, White women reported an increase from preconception to pregnancy with increased life satisfaction levels remaining stable from pregnancy to postpartum. However, Black women reported no changes in life satisfaction across these timepoints. In contrast, both Black and White women reported an increase in flourishing levels across the perinatal period, although the timing of these changes differed. Findings highlight a need for greater clinical and empirical attention to the way in which psychological well-being changes during the perinatal period to optimize health and inform strengths-based intervention targets.
